the boys were	105
there was no	104
there is a	104

as soon as	102
that it was	101
to be a	97

you want to	82
the operation of	82
up in the	81

other post of	80
i want to	79
to his feet	79
the current in	78
to one of	77
the number of	77
this is the	76
in which the	76
the boys had	76
up to the	76
new york city	76
an alternating current	76
it is a	75
other end of	75
the boy allies	75
ought to be	74
a few minutes	74
set up by	72
stream of electrons	72
in the same	71
in the air	71
it is the	71
was to be	70
of the great	70
that they were	70
to get a	69
to the other	69
they had been	69
a few moments	69
so as to	68
to have a	68
a current of	68
in front of	68
set up in	67
he could not	67
going to be	67
a matter of	66
down to the	66
it was the	66
who had been	66
of the secondary	66
of the condenser	66
so that it	66
the ends of	66
do you think	66
and it is	66
coil of the	65
of the world	65
away from the	65
for a few	65
he did not	65
it is not	64
we ought to	64
plate of the	64
rest of the	64
and these are	63
of the tuning	63
the variable condenser	63
there will be	63
just the same	62
it was not	62
is shown at	62
posts of the	62
the grid circuit	62
aerial wire system	62
there is no	62
of the air	61
sending and receiving	61
of the latter	61
all of the	61
more than a	61
in the first	61
ends of the	61
up by the	61
you have to	61
a couple of	60
one of them	60
and this is	60
must have been	60
to get the	60
by this time	60
connecting up the	60
of which is	60
the same as	60
a crystal detector	59
of the detector	59
he was a	59
the telephone receiver	59
shown at b	58
all the time	58
at each other	58
but it is	58
in a few	58
a good deal	58
to tell you	58
and he was	57
to make the	57
the resistance of	57
the same way	57
of the two	57
the young man	57
close to the	57
was going to	56
in new york	56
of the same	56
that they had	56
the sending station	56
of the filament	55
of the primary	55
the wireless telephone	55
shook his head	55
do you mean	55
which he had	55
back and forth	54
i tell you	54
of the telephone	54
the rover boys	54
over to the	54
to do it	54
as long as	54
a long time	54
but it was	54
bob and frank	53
seemed to be	53
connected with the	53
you can use	53
will have to	53
in the morning	53
the old man	53
the plate of	53
up and down	52
connect the other	52
is going to	52
as far as	52
a receiving set	52
it to the	52
you have a	52
the spark gap	51
electrode vacuum tube	51
as in fig	51
a piece of	51
do you know	51
the plate current	51
was in the	51
have to be	51

are set up	51
to be the	50
the posts of	50
in spite of	50
it is called	50
it must be	50
the wiring diagram	50
of the other	49

through the air	48
the a battery	48
as a detector	48
the crystal detector	48
that is the	48
to be able	47
to use a	47
the edge of	47
of the grid	47
most of the	47
the name of	47
will be a	47
you will have	47
and there was	47
and they were	47
dots and dashes	47
this is a	47
as the boys	46
of the posts	46
one of these	46
turns of wire	46
the other hand	46
wiring diagram for	46
of the tube	46
you can see	46
at that moment	46
had not been	46
one post of	46
the side of	46
in the united	46
in touch with	45
of the boys	45
of the aerial	45
at the other	45
then connect the	45
the first time	45
and connect the	45
and in a	45
a telephone receiver	44
is shown in	44
with a smile	44
exactly the same	44
as he had	44
b in fig	44
tell you what	44
a chance to	44
edge of the	44

going to do	44
to the plate	44
kind of a	44
way to the	44

of the circuit	43
at a time	43
when it is	43

had to be	43
get out of	43
is the same	43
by the way	43
with the other	43
of the coil	43
more or less	42
to the boys	42
the center of	42
to do is	42
have to do	42
in the wiring	42
the man who	42
high frequency currents	42
use of the	42
the alternating current	42
wireless telephone transmitter	42
in a circuit	42
to and fro	42
parts of the	42

a moment later	42
the middle of	41
at the end	41
the terminals of	41
if you have	41

do is to	38
two or three	38
to do with	38
the frequency of	38
grid of the	38
the work of	38
the boy scouts	38
that it will	38
to think of	38
what is it	38
and how to	38
in the other	37
number of turns	37
look at the	37
used as a	37
you know that	37
we can get	37
secondary coil of	37
out into the	37

was able to	37
on receipt of	37
for some time	37
the first place	37
to see the	37

that the boys	37
was one of	37
if you want	37
the grid leak	36
the direction of	36

bob and joe	35
the part of	35
a coil of	35
by all booksellers	35
in the city	35
of one of	35
coil and the	35
of the most	35
he went on	35
as a matter	35
to say that	35
at the receiving	35
by the time	35
the human voice	35
back into the	35

so that they	34
said captain folsom	34
we want to	34
a stream of	34
of the variable	34
the plate and	34
he was not	34
and with a	34
in a low	34
he was going	34
flow through the	34
the other day	34
to take the	34
number of electrons	34
and at the	34
detector receiving set	34
how do you	34
but he was	34
loose coupled tuning	34
of the town	34
they reached the	34

and if you	33
on the ground	33
out of a	33

it seems to	33
was on the	33

to try to	33
on the grid	33
looked at each	33

the grid is	31
of this to	31
as they are	31
out to the	31

so far as	31
that you are	31

the latter with	31
for you to	31
that they would	31
that was a	31
charge of the	31

to see what	31
in the case	31
strength of the	31
continuous wave telegraph	30
of his own	30
we can do	30
boy allies with	30
and he had	30
them to the	30
what to do	30
and you can	30
connected in series	30
out of his	30
on top of	30
down on the	30
with alternating current	30
i suppose you	30
and on the	30
good deal of	30
of the room	30
the storage battery	30
you know what	30
the result is	30
be glad to	30
the story of	30
for us to	30
the strength of	30

volt direct current	30
he had no	29
now and then	29
and then the	29
the midst of	29
he would be	29
is made to	29
of a condenser	29
and see what	29
a short time	29
is connected with	29
mounted on a	29
the grid and	29
of the day	29
as if he	29
came to the	29
for a while	29
you are going	29
i told you	29
that they could	29
this was the	29
as they had	29
did not know	29
in the last	29
what are you	29
might have been	29
of the sea	29
you can buy	29
we have a	29
other terminal of	29
the form of	29
on to the	29
of the men	29
on the floor	29
a few seconds	29
of the plate	29
to put up	29
i should say	28
which is shown	28
tube is used	28
to get out	28
the inductance of	28

action of the	28
up the parts	28
they would have	28
it has been	28

for a time	28
fact that the	28
the spark coil	28
is known as	28
he had to	28
frequency of the	28
that you can	28
and so on	28
the wireless telegraph	28
as he was	28
to set up	28
in this way	28
when i was	28
and it will	28
or storage battery	28
to the filament	28
take care of	28
there was nothing	28
due to the	28
many of the	28
new york illustration	28
by the radio	28
man who had	28
the case of	28
apparatus you need	28

him on the	27
of the night	27
one of his	27

i was just	27
been able to	27
you know the	27
herb and jimmy	27
when they are	27

able to get	27
the two men	27
they would be	27
all over the	27

other side of	27
the two boys	27
out of this	27
tuning coil and	27
thing to do	27
a variable condenser	27
the microphone transmitter	27
put up a	27

inches in diameter	27
do you suppose	27
that he could	27
the whole thing	27
pole of the	27

to the positive	27
know how to	27
of the apparatus	27
returned to the	27

he saw the	26
all of which	26
the idea of	26
the door of	26

said his father	26
with the ground	26
a distance of	26
must be a	26

the negative plate	26
direction of the	26

and i have	26
the three boys	26
and began to	26
be used for	26
it was only	26
to see you	26
current through the	26

the house and	26
coils of the	26

in the midst	26
to find the	26
of them are	26
a great deal	26
to one end	26
a capacitance of	26
i can see	26
he was in	26
is a very	26
it is shown	26
moving picture boys	26
the kind of	26
be used to	26
vacuum tube amplifier	26
at ocean point	26
search for the	26
ought to have	26
the new york	26
it consists of	26
if it is	26

of the kind	26
the size of	26
a fixed condenser	26
of vacuum tube	26
oscillation choke coil	26
through the ether	25
the wireless room	25
i am not	25
the boys and	25
to be used	25
i have been	25
as fast as	25
in the meantime	25
and i guess	25
tube acts as	25
seems to have	25
you must have	25
to be done	25
to do this	25
a length of	25

all the way	25
said don ernesto	25
volt storage battery	25
on their way	25
on board the	25
the radio plant	25
of the united	25
of it and	25
i am going	25
the bottom of	25
a storage battery	25
your receiving set	25
with a single	25
as you can	25
to flow through	25
a spark coil	25
in the circuit	25
a resistance of	25

you will find	25
impressed on the	25
you do not	25
would like to	25
more and more	25
the closed circuit	25
corporation of america	25
i should think	25
the same thing	25
the ground wire	25
i wonder if	25
in the cabin	25
the way the	25
him in the	25
each other in	25
filament and the	25
their way to	25
or positive electrode	24
the telegraph key	24
seemed to have	24
at the bottom	24
at the moment	24
the positive plate	24
and a few	24
to be seen	24
the next morning	24
in charge of	24
cycles per second	24
of the b	24
i think we	24
of the big	24
the course of	24
it was all	24
in the ground	24
tube detector receiving	24
that we can	24

there is an	24
were able to	24
if there is	24
amplifying receiving set	24
here in the	24

and all the	24
the door and	24
with one post	24
which it is	24
from the other	24
closed oscillation circuit	24
must be used	24
the oscillation transformer	24
in such a	24
there was an	24

in the coil	23
want you to	23
the motor boat	23
can be connected	23
you can do	23
as for the	23
the electric current	23
is a good	23
it and the	23
the result of	23
you can make	23
a look at	23

what is the	17

he was thinking	17
listen in on	17

they had a	17

there may be	17
it does not	17
she was a	17
find out what	17
that was all	17
it with the	17
looked at him	17
the telephone receivers	17
the older man	17

be a good	17
over and over	17
he had taken	17
to give it	17
one of us	17
what it is	17
i thought you	17
as to what	17
had to do	17
number of volts	17
few minutes later	17

down at the	17

in his eye	17
a look of	17

the air was	17
on his face	17

the ground and	17
if we had	17
on the water	17
him to be	17
in a minute	17
and of the	17

a wiring diagram	17
go back to	17

wireless receiving set	15
told me that	15

a very good	15
that is what	15
it is connected	15
of the long	15

set up and	15
not in the	15

in a little	15
none of the	15
you can find	15
he was to	15
used to be	15
as he turned	15
we might as	15
give it to	15
said to be	15
and tell him	15
i know it	15
in communication with	15
they are called	15
you think you	15
have had a	15
down into the	15
he was so	15
of the island	15
to see them	15
that the current	15
the battery is	15
telephone and telegraph	15
make sure that	15
one vacuum tube	15
and i will	15
a good many	15
to look after	15
to hear it	15
he had done	15
wait a minute	15
then you can	15
connected in parallel	15
to a point	15
and find out	15
and there are	15
have been in	15
back in a	15

the young fellow	15

but you can	15
the next few	15
was going on	15
that they will	15
at the foot	15
and receiving sets	15
in the beginning	15
that i have	15
the next instant	15
on the spot	15
by the same	15
up to him	15
i have just	15
and it would	15
of wave lengths	15
is made and	15
at one time	15
which they were	15
after you have	15
so that a	15
the next moment	15
if you were	15
one hundred and	15
that would have	15
him in a	15

the receiving end	15
in a small	15
i had to	15
it up to	15
the ferberton prize	15
i can tell	15
to his father	15
if they had	15
the transformer and	15
on the island	15
the last of	15
the battery current	15
they came to	15
direct current is	15
to make up	15
secret of the	15

shall have to	15
as we can	15
boys series by	15
that in the	15

and the second	15
of the parts	15
have to have	15
here on the	15

the wire is	15
his face was	15
as we say	15
he might have	15
portion of the	15
coil to the	15
sides of the	15
this can be	15
to take up	15
that they are	15
thought of that	15
for one of	15
the audion characteristic	15
i have to	15
there is to	15
time they had	15
